| ## ◆ out_of_range
using nlohmann::basic_json::out_of_range = detail::out_of_range
This exception is thrown in case a library function is called on an input parameter that exceeds the expected range, for instance in case of array indices or nonexisting object keys. Exceptions have ids 4xx.
name / id | example message | description
--- | --- | ---
json.exception.out_of_range.401 | array index 3 is out of range | The provided array index i is larger than size-1.
json.exception.out_of_range.402 | array index '-' (3) is out of range | The special array index `-` in a JSON Pointer never describes a valid element of the array, but the index past the end. That is, it can only be used to add elements at this position, but not to read it.
json.exception.out_of_range.403 | key 'foo' not found | The provided key was not found in the JSON object.
json.exception.out_of_range.404 | unresolved reference token 'foo' | A reference token in a JSON Pointer could not be resolved.
json.exception.out_of_range.405 | JSON pointer has no parent | The JSON Patch operations 'remove' and 'add' can not be applied to the root element of the JSON value.
json.exception.out_of_range.406 | number overflow parsing '10E1000' | A parsed number could not be stored as without changing it to NaN or INF.
json.exception.out_of_range.407 | number overflow serializing '9223372036854775808' | UBJSON and BSON only support integer numbers up to 9223372036854775807.
json.exception.out_of_range.408 | excessive array size: 8658170730974374167 | The size (following `#`) of an UBJSON array or object exceeds the maximal capacity.
json.exception.out_of_range.409 | BSON key cannot contain code point U+0000 (at byte 2) | Key identifiers to be serialized to BSON cannot contain code point U+0000, since the key is stored as zero-terminated c-string
  Example The following code shows how an `out_of_range` exception can be caught. 1 #include <iostream> 2 #include <nlohmann/json.hpp> 3 4 using json = nlohmann::json; 5 6 int main() 7 { 8 try 9 { 10 // calling at() for an invalid index 11 json j = {1, 2, 3, 4}; 12 j.at(4) = 10; 13 } 14 catch (json::out_of_range& e) 15 { 16 // output exception information 17 std::cout << "message: " << e.what() << '\n' 18 << "exception id: " << e.id << std::endl; 19 } 20 } Output (play with this example online):
      message: [json.exception.out_of_range.401] array index 4 is out of range
      exception id: 401
  The example code above can be translated with
      g++ -std=c++11 -Isingle_include doc/examples/out_of_range.cpp -o out_of_range
